One way of approaching such modelling uncertainties is to build explicitly a number of likely models, refine them and examine the difference maps carefully to see whether you can convince yourself that one model is clearly better than the others. At least then you will know whether the alternati

Dear Reza, I would back Jon’s idea of looking at homologues, although this does depend on how close the homologue is. For example, if your protein has a “P” loop, with the Walker A sequence motif, then I think it would be very surprising if the nucleotide bound in different wa
